Overnight battery drain
When I left to sleep, I remembered that my phone have charged above 65 percent battery in the night. When i check my phone in the next morning, it was completely switched off without any apps running background in it.
Also checked my device battery activity, there is no app running or background activity overnight. My current iOS version is 16.3.(Battery health is 97 percent)
Is that any indication of problem or I want to restore IOS version ?
please refer my attached images and kindly tell me a solution.
This was the first time happening to me.
Device- iphone 13 mini.
